My profile expertises are in Execution, Project Management and Design in civil engineering field. How Potential is my Profile for a employer?

what's potential, the profile or the employer ? the question seems intriguing and would appreciate your rewording it.

The actual meaning of this question escapes me but let me try anyhow at my own risk:

broad diversified cross knowledge allows to pick

the most suited solution for a given problem and,

above all, is a much more fun and rewarding way of working.

this is determined by employer intersets 

Actually don't have clear answer...prefer to wait for answers by professionals

I think this is good for you
